时距估计任务中的间断期望效应

使用单任务研究程序，采用引入提示线索的方法，以产生时距作为反应指标对存在间断的时距估计任务中的间断期望效应和提示线索效应（注意效应）进行系统考察，并对间断时距的效应、产生时距与等待时距的关系问题作出进一步探讨。结果表明，间断位置（等待时距）因素是被试时间判断的主要线索，被试的产生时距随着等待时距的增加而延长。间断实验中表现出极其显著的提示线索效应，此效应既增加了时距估计的变异，又延长了被试的时距估计。无间断实验条件下，被试表现出显著的间断期望效应，被试对间断的期望有损于时间估计。

The Effect of Expecting of a Break in Time Estimation Task

Based on previous theories and studies, we selectly use the prospective paradigm and creatively use the single - task program in this research. Experiments are conducted with geometric stimulus presented in visual mode, and the analysis of variance are made on data from this research. By taking perspectives of psychophysics, we aim at exploring the effect of break position （waiting duration） , break duration, and the effect of expecting a break. At the same time, the relationship between duration production and the break posi- tion is further investigated. The results showed that the effect of the break position （ waiting duration） is significant. In trails without breaks, the cue factor shows a significant experimental effect. This fact reflects that expecting of a break can lengthen the time estimation.
